P2000SCMC Working Principle

The P2000SCMC switching circuit utilizes a thyristor controlled analogue switch that senses external parameters such as temperature, pressure, voltage, current, or frequency, and then automatically adjusts the switching control signal accordingly. The device is based on a floating switch, which allows it to be used in both single-phase and three-phase power systems. The switch itself is managed by a control circuit, which is connected to the thyristor through a separate control line. The control circuit consists of a voltage controlled oscillator (VCO), a control circuit for generating a control signal, and a logic circuit for generating a logic control input.

The voltage controlled oscillator (VCO) is used to produce a regular switching frequency. The control signal from the VCO is processed through a logic circuit, which computes the input signals from the external sensor or other variables, and produces a logic control signal, which is then applied to the control of the thyristor. The control output from the thyristor is then used to control the power switch. When the electrical parameters reach the target value, the thyristor will switch off power control. As a result, the power switch automatically adjusts power levels to the desired level.

Conclusion

The P2000SCMC is an ideal high voltage, high current switch for any application requiring reliable and precise control of electrical power. It utilizes a thyristor based analogue switch and control circuit to adjust power levels as required. It is an ideal solution for a wide range of aerospace, automotive, industrial, and medical applications.
